I am on Ubuntu 9.10 Karmic and have a Belkin G Wireless router with WPA2 Personal Security. Whenever I try to connect, it keeps prompting for the password over and over.
Any ideas how to get the connection working?
I've experienced this problem countless times using KDE.
Try removing your driver (modprobe -r [driver]) and then reloading it, then try to restart NetworkManager.
Also if your AP has security try disabling it and then accessing it non-securely.
I also had bad experience with those wireless adapters. I have a N access point, and although I had no major issues connecting from my Linux netbook, my wife, under Vista, was getting disconnected all the time. I bought a standard D-Link N adapter, and the problem went away.
